1 Claim.

This invention relates generally to machines for washing clothes, andparticularly to an electrically propelled machine of small dimensions ascompared with the ordinary machine of the household type.

The main object of this invention is to provide a novel form of washingmachine particularly adapted for small washings and for washing delicatefabrics. r

The second object is to construct a machine which will be exceedinglysimple to manufacture and assemble and which will be quiet in operationand also extremely durable in service.

These, and other objects, will become more apparent from thespecification following as illustrated in the accompanying drawings, inwhich:

Fig. l is a side elevation of the machine.

Fig. 2 is an end elevation.

Fig. 3 is a vertical section taken along the line 3-3 in Fig. 1.

Fig. 4 is a vertical section taken along the line 4-4 in Fig. 1. K

Fig. 5 is a vertical section taken along the line 5-5 in Fig. 3.

Similar numbers of reference refer to similar parts throughout theseveral views.

Referring in detail to the drawings, there is shown a pair of end framesand 11 which are held in spaced relationship by the rods 12.Mountedbetween the frames 10 and 11 is a washing cylinder 13 whose end14 is provided with a trunnion 15 which journals in the frame 10. H Theend 16 of the cylinder 13 is provided with an elongated trunnion 17which has an opening 18 formed therethrough and a provision at its outerThe trunnion 17 journals in the wall 20 of the frame 11, which differsfrom theframe 10 inasmuch as it forms a housing or gear case for theoperating mechanism. The frame 11' has formed therein an opening 21provided with a cover plate 22 through which projects the end 19 of thetrunnion 17.

On the wall 20 is mounted a motor 23 to which energy is supplied throughthe cord 24. The motor 23 drives the shaft 25 through the flexiblecoupling 26. The shaft 25 carries a worm 27 which meshes with the wormwheel 28 mounted on a stud bolt 29 projecting from the side of the plate30 which is carried by the pillars 31, which are carried by the wall 32which wall is spaced a short distance from the wall 20. The worm wheel28 serves as a crank by means of which crank the connecting rod 33imparts a rocking motion to the cylinder 13 through the lever 34 securedto the trunnion 1'7.

It is desirable to provide the cylinder 13 with a removable handledcover35 and also a waste pipe 36, which is controlled by the small lever37. The fioor 38 of the frame 11 is provided with a drain opening 39through which water from the waste pipe 36 can pass.

The operation of the device is as follows: 1

Clothes, water and a cleansing agent are placed within the cylinder 13and the cover 35 is put into position (as shown in Fig. 5) after whichcurrent is supplied to the motor 23 which causes the worm Wheel 28 torevolve, and, through the members 33 and 34, to rock the cylinder 13,which is incidentally provided with a number of ribs 40 and 41 for thepurpose of bringing about a better tumbling action for the fabrics.

The washing operation can be continued as long as desired, after whichthe articles can be removed with or without allowing the water to escapethrough the waste pipe 36.

It can be seen that by this construction an exceedingly simple and rigidform of machine is produced and one of such small weight as to permt itsselling through the mail, which is highly desirable with this class ofmerchandise.

We are aware that many forms of washing machines have been constructedin the past, and it is not our intention to broadly cover thisinvention; it is rather understood that we do intend to cover all formsand modifications thereof as fall fairly within the appended claim.

We claim:

In a washing machine, the combination of a pair of spaced side frames,one of said frames being hollow and having a catch basin formed therein,a rockable water cylinder mounted between said frames having anextending outlet projecting into said catch basin, and means within saidhollow standard for rocking said container.
